我有一个 flutter 应用程序，上面还有一个函数文件夹。下面是文件位置：

   \n

我在新建的电脑上运行 Windows 11（所以可能缺少某些东西？），其他开发人员在 mac 上运行，我已将函数文件夹的 3 个文件的 EOF 序列更改为 LF，我还运行了这两个函数文件夹内的命令

\n

npm install firebase-functions@latest firebase-admin@latest --save

\n

npm install -g firebase-tools

\n

npm 版本是 8.1.2

\n

节点版本是v16.13.1

\n

firestore.indexes.json 是：

\n

{\n  "indexes": [\n    {\n      "collectionGroup": "something1",\n      "queryScope": "COLLECTION",\n      "fields": [\n        {\n          "fieldPath": "created",\n          "order": "DESCENDING"\n        },\n        {\n          "fieldPath": "something2",\n          "order": "DESCENDING"\n        }\n      ]\n    },\n    {\n      "collectionGroup": "something3",\n      "queryScope": "COLLECTION",\n      "fields": [\n        {\n          "fieldPath": "something4",\n          "order": "ASCENDING"\n        },\n        {\n          "fieldPath": "something5",\n          "order": "DESCENDING"\n        }\n      ]\n    }\n  ],\n  "fieldOverrides": []\n}\n\n

\n

.elslint.js 是

\n

module.exports = {\n  "root": true,\n  "env": {\n    es6: true,\n    node: true,\n  },\n  "extends": [\n    "eslint:recommended",\n    "google",\n  ],\n  "rules": {\n    quotes: ["error", "double"],\n  },\n  "parserOptions": {\n    "ecmaVersion": 2020,\n  },\n};\n

\n

package.json 是

\n

  "name": "functions",\n  "description": "Cloud Functions for Firebase",\n  "scripts": {\n    "lint": "eslint .",\n    "serve": "firebase emulators:start --only functions",\n    "shell": "firebase functions:shell",\n    "start": "npm run shell",\n    "deploy": "firebase deploy --only functions",\n    "logs": "firebase functions:log"\n  },\n  "engines": {\n    "node": "14"\n  },\n  "main": "index.js",\n  "dependencies": {\n    "axios": "^0.24.0",\n    "device-detector-js": "^3.0.0",\n    "firebase": "^9.2.0",\n    "firebase-admin": "^10.0.1",\n    "firebase-functions": "^3.16.0"\n  },\n  "devDependencies": {\n    "eslint": "^8.1.0",\n    "eslint-config-google": "^0.14.0",\n    "firebase-functions-test": "^0.3.3"\n  },\n  "private": true\n}\n

\n

请记住，在运行 Windows 10 的旧电脑中，我可以通过仅更改为 LF 并运行上述命令来进行部署。

Answer 1

只需尝试创建一个新的文本文件并将生成的文件的内容复制到新文件中。然后覆盖新文件firestore.indexes.json

很明显生成的json文件存在格式问题。
